Question 402842
I'll do the first one to get you started.



{{{2/5 - 3/x = 1/(5x) }}} Start with the given equation.



{{{2x - 15 = 1 }}} Multiply EVERY term by the LCD 5x to clear out all the fractions.


{{{2x=1+15}}} Add {{{15}}} to both sides.



{{{2x=16}}} Combine like terms on the right side.



{{{x=(16)/(2)}}} Divide both sides by {{{2}}} to isolate {{{x}}}.



{{{x=8}}} Reduce.

Answer:


So the answer is {{{x=8}}}
